Please read on the concept of Mass and Weight here

Mass is the amount or quantity of matter (substance) contained in a body. For instance, everything you are composed of, both from within and outside will make up your mass.

Mass is constant throughout the universe. You will have the same mass on earth and moon respectively.

Mass is measured in gram or kilogram and it's quite different from weight.
